I don’t expect that you will be able to transfer in to a tier 1 law school with your undergrad academic record and LSAT. Here is what Harvard law looks for in transfer applicants as one example. https://hls.harvard.edu/jdadmissions/apply-to-harvard-law-school/standards-for-admission/
If you want to attend law school now your best bet is to enroll at a school where you have been accepted and work to excel there. Consider the employment record of graduates if you choose a law school from your acceptances. You cannot count on a transfer to a tier 1 law school - or any law school for that matter - working out. Assume you will stay at the law school you start at. If you want to throw in a few transfer applicantions that is fine-- but I’d apply more broadly than just to the top tier schools.
If you want to work for a few years before law school, retake the LSAT, and then reapply to a broad range of schools that is another option (there is no guarantee of better results than you already have though).
